BROADSOFT INTRODUCES IP VOICE AND IP CENTREX FOR PDAs WITHIN 802.11 WIRELESS NETWORKS

Demonstrates Ease of Adding New Applications to BroadWorks

GAITHERSBURG, MD, October 21, 2002 -- BroadSoft Inc., the leading provider of voice applications and servers, today announced that enterprise users of Voice over Internet Protocol (VoIP) services based on BroadSoft's industry-leading BroadWorks solution can now add voice services to any 802.11-enabled device, such as Personal Digital Assistants (PDAs), laptops and business phones.

BroadSoft is partnering with SJlabs, a leading provider of soft clients for mobile devices and industrial terminals, to develop this new application. This announcement also introduces SJlabs' SJphone™, the first Session Initiation Protocol (SIP)-based soft client for PDAs. The combination of technologies from these two innovative developers will enable users to get, for the first time, a complete suite of business telephony services over any PDA based on Microsoft's CE operating system within a wireless 802.11 network.

This new application also demonstrates how easily service providers can add new services when using BroadWorks™. Because it is standards-based and supports the most widely used protocols - in this case 802.11 and SIP - initial interoperability between these two products was achieved in a matter of hours. SIP has become the de facto standard and building block for developing and delivering innovative communications services.

"Our carrier customers are using BroadWorks because its broad portfolio of applications enables them to retain customers and attract new ones by providing innovative and reliable services. We believe the addition of Wi-Fi voice to PDAs is another example of how using BroadWorks can help service providers further differentiate themselves," said Michael Tessler, president and CEO of BroadSoft. He added that the combination of 802.11's broadband speed capabilities and BroadWorks' wide array of business services will enable PDAs to provide much more than traditional phone services.

Wireless Fidelity (Wi-Fi), as 802.11 is called, is available to users within the area covered by a wireless LAN. Until now, Wi-Fi has primarily been used for email and other data applications on laptop and desktop computers. With BroadSoft's announcement today, the flexibility and high-speed capabilities of 802.11 Wi-Fi is extended to voice services and PDAs, enabling users to walk around an office equipped with a wireless LAN, still "connected" but untethered to a desk phone. In addition to having all phone features, users also have access to all of their BroadWorks-based services such as conferencing and call forwarding.

802.11 technology is rapidly gaining acceptance. The Gartner Group estimates that at least 20% of large corporations have wireless LANs. In addition homes, hotels, airports and even coffee shops are increasingly offering wireless LANs. 802.11 offers high-speed access of up to 54 megabits per second, over 30 orders of magnitude faster than the 144 kilobits per second of 3G (third generation) wireless phones.

"BroadSoft's integration of our voice client and 802.11 with BroadWorks significantly advances enhanced communications services. We look forward to working with BroadSoft and its customers to deliver this useful application to enterprise users," said Edward Gurary, vice president of sales and business development for SJlabs. "Partnerships with voice application providers like BroadSoft will provide our customers access to the new communication services and solutions".

BroadWorks is the industry's first integrated system of voice applications and servers enabling service providers to deliver basic and enhanced voice services to enterprises. Using BroadWorks, service providers and their customers can manage administrative functions using its patented web-based portal, CommPilotä. Further, BroadWorks can scale to support millions of subscribers and delivers 99.999% total system availability.
